27 Claims. (Cl. 199-19) This invention relates to typographical composin machines such as Linotype machines of the general organization represented in Letters Patent of the United States to O. Mergenthaler, No. 436,532, wherein circulating matrices are released from a magazine in the order in which their characters are to appear in print and then assembled in line, the composed line transferred to the face of a slotted mold, the mold filled with molten metal to form a slug or linotype against the matrices which produce the type characters thereon, and the matrices thereafter returned through distributing mechanism to the magazine from which they started.

More particularly, it relates to that class of mixing machines designed to handle matrix fonts which differ from one another in the size and number of characters, for example, the regular ninety character text fonts used exclusively for the composition of straight. matter, and the special seventy-two character fonts used for the composition of head letter or display matter.

The matrix storage magazines employed in machines of this class are of the standard size and shape but differ in the number and arrangement of their matrix channels, the regular magazines being provided with ninety-one channels spaced apart in the usual way to accommodate the matrix columns of the text fonts, while the display magazines are provided with but seventythree channels spaced apart in a different way to accommodate the matrix columns of the larger special fonts. In certain of the later models (see the patent to Frolander et al. No. 2,155,588), the magazines (four in number) are arranged in superposed pairs and are movable as a unit upwardly and downwardly in the machine frame so that the upper or lower pair may be brought into operative relation with the assemblin and distributing mechanisms as desired. Each of the several magazines is equipped with a bank of escapements controlling the release of the matrices therefrom, and the actuating devices therefor are adjustable to connect the finger keys of the keyboard with the escapements of either of the magazines in use.

The entrance to the assembling mechanism includes a relatively fixed throat section arranged to receive matrices released from the upper magazine of a selected pair, and a movable throat section capable of adjustment so as to conduct matrices passing from the fixed throat section, or matrices released from the lower magazine of the selected pair, into a channeled raceway or front plate common to both magazines. The movable throat section is pivotally mounted in the machine frame so that it may be swung to and fro against fixed stops which locate it in its different adjusted positions, and power operated mechanism controlled by a finger key is employed to effect its adjustments. While the mechanism heretofore employed functions satisfactorily, it has been found in practice that occasionally the movable throat section will rebound slightly as it engages the fixed stops or for some other reason will become accidently displaced and cause transposition of the matrices as they are assembled in line or clogging of theassembler entrance. Fur thermore, it frequently happens that, before the movable throat section ha had time to respond to its adjusting mechanism, a fast operator will have actuated one or more keys of the keyboard and cause the release of matrices from the origi nally selected magazine rather than the newly selected magazine. As a result, and in addition to the inconvenience and annoyance involved, considerable time will be lost before the trouble is rectified.

The present invention aims toovercome these and other difficulties and is directed primarily to an improved power operated mechanism which may be instantly conditioned to effect the individual adjustments of the movable throat section and the escapement actuating devices in the proper manner required. In the preferred embodiment illustrated, the improved mechanism includes a pair of actuators carried by a constantly reciprocating slide and adapted, by the operation of a finger key, to swing the throat section during either stroke of the slide to one or the other of its different adjusted positions. The improvements also include automatic means for positively locking the throat section against accidental displacement in its adjusted positions. The construction and operation of the parts will best be understood from the detailed description to follow.

In the accompanying drawings, the invention is shown merely in preferred form by way of example and as applied to a machine of a particular class, but it should be understood that it is equally applicable to machines equipped with magazines adapted to contain only the ninety character text fonts or only the seventy-two character display fonts and wherein the escapement actuating devices require no special adjustment to effect the release of matrices from the individual magazines of a selected pair. Moreover while the invention has herein been shown and described as applied to the main magazines,

it is equally applicable to the side or auxiliary magazines. In other words, the invention is not limited to any specific form or embodiment except insofar as such limitations are specified in the claims.

As shown in Fig. l, the machine is equipped with four superposed magazines A A A A capable of being raised and lowered in the machine frame by operation of a crank handle B in order to bring either the upper or lower pair of magazines into operative relation with the assembler entrance C and the distributing mechanism (not shown). The second and fourth magazines A and A are of the regular or standard form and adapted to contain the ordinary ninety character text fonts, whereas the first and third magazines A and A are of a different form and adapted to contain the special seventy-two character display fonts.

The assembler entrance C includes an upper throat section C having its partition plates 0 spaced apart at their upper ends to cooperate with the matrix columns of the magazine A or A a lower adjustable throat section C having its partition plates 0 differently spaced apart to cooperate with the matrix columns of the magazine A or A and a fixed partitioned bridge member C arranged to register with the magazines A and A and over which the matrices are adapted to pass when they are released therefrom. The throat section C is hingedly mounted in front side brackets T of the machine frame so that it may be swung forwardly when desired for access to the magazines; and the throat section 0 is fastened to a horizontal rock shaft C journaled at its opposite ends in bearing portions T of said brackets and provided with a crank arm 0 operable to swing the throat section forwardly and backwardly in effecting its adjustments. An overhead banking screw u, mounted at the upper end of a fixed upright bracket U and arranged to engage the crank arm C locates the throat section C in its forwardly adjusted position in registry with the lower end of the throat section C while a set screw 0 carried by the throat section C and arranged to engage a stop shoulder t projecting inwardly from one of the side brackets T, locates said throat section in its rearwardly adjusted position in registry with the bridge member C In either of its adjusted positions, the throat section C is adapted, in conjunction with a yielding front guide plate C (Fig. 1), to conduct the matrices released from the selected magazine into a fixed vertically disposed channeled raceway C from which the matrices are directed to the assembler proper for composition in line.

Each of the several magazines is provided with matrix releasing escapements a; and the actuating devices therefor include, generally, a series of fore-and-aft pivoted levers D, a corresponding series of actuating slides D carried by the throat section C and a series of small actuating elements D mounted in the throat section C and operable by the slides D The levers D are controlled from a keyboard E through the medium of two sets of vertical reeds D D and a series of horizontally disposed levers F, which latter are mounted in a support F adjustable thereby to and fro to connect the keyboard with one set of reeds or the other. The reeds D of the front set correspond in number and spacing with the matrix channels of the display magazines A and A while the reeds D of the rear set correspond in number and spacing with the matrix channels of the regular magazines A and A When the throat section C and the support F occupy their forwardly adjusted positions as shown in Fig. 1, an operative connection between the keyboard E and the escapements of a selected display magazine will be established through the front set of reeds D and conversely, when said throat section and support occupy their rear wardly adjusted positions, an operative connection will be established between the keyboard and the escapements of a selected regular magazine through the rear set of reeds D The actuating slides D under the first adjustment, are connected with the escapements of the upper magazine by means of the intervening actuating elements D and, under the second adjustment, are connected directly with the escapements of the lower magazine.

As thus far described, the parts, their construction and the manner in which they cooperate are or may be the same as in the commercial Linotype machines of the class described and in themselves constitute no part of the present invention.

According to the present invention, the adjustments of the throat section C and the support F for the levers F (see Figs. 3-6 and 8) are effected by a constantly reciprocating slide G equipped with a pair of actuating elements G G adapted to control the operation of a fore-and-aft rocking lever H presenting a pair of studs h h mounted in lateral protuberances h on said lever. As shown best in Fig. 6, the lever H is fastened about midway of its length to a horizontal rock shaft H and formed at its rear end with a counterbalancing weight it, the purpose of which will later appear. The rock shaft H is journaled in a fixed bearing bracket H and provided with an arm H adapted by operation of the lever to control the adjustments of the support F the intermediate connections comprising a bail-like lever I pivotally mounted on a horizontal rod 1 and formed with two spaced apart arms I and F. The arm I (Figs. 1 and 2) is connected with the support F by a short fore-and-aft link 1, while the arm I (Fig. 6) is arranged alongside the arm H of the rock shaft H and is appropriately attached thereto by an anti-friction pin and slot connection i Small brackets I secured to front side members 'I of the machine frame, give the necessary support to the rod I The arrangement is such that rocking of the lever H turns the shaft H in opposite directions and, through the bail-like lever I, causes the support F to be shifted forwardly and backwardly to one or the other of its two different adjusted positions to connect the keyboard E with the front or rear set of escapement actuating reeds D D The connections between the rocking lever H and the assembler throat section C (see Figs. 1, 2, 4, 5 and '7) include a long vertical rod J rising from the front end of the lever H and attached thereto by means of a pin and slot connection h At its upper end, the rod J is freely mounted on a stud J fastened transversely in a lever J and projecting beyond the same to engage in a short angularly disposed slot C formed in the aforementioned crank arm C The lever J (Fig. 7) is pivotally mounted on the rock shaft C in juxtaposition to the crank arm C and is held in place against axial displacement thereon by a collar C the latter being secured to the shaft and located in a bifurcated portion of the lever J When the lever His rocked in a clockwise direction (Fig. 1), the lever J will be swung upwardly and, through its connection with the crank arm C of the rock shaft 0*, will swing the throat section C forwardly to its adjusted position, as shown. At the same time and as described above, the shaft H will be turned in the appropriate direction to effect a corresponding or forward adjustment of the lever support F On the other hand, when the lever H is rocked in the opposite direction, the operation of the parts will be reversed and both the throat section C and the lever support F will b moved simultaneously to their rearwardly adjusted positions. The slot C for reasons later to be pointed out, permits a slight lost motion to take place between the crank arm 0 and its actuating lever J prior to the operation of the rock shaft C in adjusting the throat section C To facilitate its movements, the throat section C is counterbalanced by a pull spring C (Figs. 1 and 2) arranged between a link 0 depending from the crank arm C and a screw eye adjustably mounted in an anchor pin u fastened to the upright bracket U. i

The constantly operated reciprocating slide G, for effecting the adjustments of the throat section C and the lever support F is mounted for vertical movement in a fixed housing bracket V and operated from an eccentric K by means of a vertical connecting rod K As shown in Fig. 3, the eccentric K is formed on the hub of a gear wheel K which is driven from the so-called intermediate shaft L through the medium of a friction clutch M and a small pinion M journaled on an extension L of said shaft. For purposes of safety and appearance, the gear wheel K and pinion M as V of said bracket, and the slide G being arranged in spaced apart guide members V on the same side wall and retained therein by corresponding gib plates V The clutch M (Fig. 3) comprises merely a fiber disc M mounted freely on the drive shaft L between a collar M formed at one end of the pinion M and a metal disc M fastened to one of the shaft bearings L. A compression spring M positioned behind the pinion M and reacting against a collar L on the shaft extension L holds the clutch members constantly engaged and determines the power of the friction drive. To regulate the tension of the spring M the collar L is provided with a clamping screw 1 which permits it to be adjusted axially on the shaft extension L when desired.

The actuating elements G and G for the rocking lever H (Fig. 3) both rise from a common pivot stud g riveted into lower end of the slide G and may be swung a limited distance in opposite directions to different adjusted positions. The actuator G presents a head portion G3 having hook-shaped projecting ears 9 g adapted during a downward stroke of the reciprocating slide G to engage from above one or the other "of the studs h k on the lever H, and similarly the actuator G which is somewhat shorter than the actuator G presents a head portion G having straight edged projecting ears 9 9 adapted during an upward stroke of the slide G to engage from below one or the other of said lever studs. Normally, the actuators are idle and may occupy either the position shown in Fig. 8 or that shown in Fig. 12 while the slide is in motion. However, whenever their angular position is reversed, a projecting ear of one or the other of the actuators, through its engagement with the stud h or the stud it will actuate the lever. H irrespective of the direction in which the slide happens to be moving. To locate the actuators in their reversed positions, the slide G is provided at its upper end with a stop pin G which projects laterally therefrom through an open slot G formed in the upper edge of the actuator G and terminates within a circular aperture G formed transversely in the actuator G Reversal of the actuators G and G (see Figs. 8, 10, 12 and 13) is effected by the operation of a vertically disposed primary lever N formed at its upper end with an over-balancingweight N and connected with both actuators through a similarly disposed secondary lever N and a relatively short horizontal link N the latter having a cross pin connection N with the lever N and being connected to the lower extremity of the lever N At its lower end, the lever N is provided with a bearing N wherein is mounted a short horizontal shaft N equipped at its opposite ends with a pair of antifriction rollers n n engaging corresponding track sections 0 v rising from the bottom wall of the fixed housing bracket V. The roller n (Fig. 9) is confined in a closed slot 11 the lower side wall of which coincides with the track section 0 and the shaft N about which the lever N; is adapted to swing, is shiftable to and fro within the limitations of said slot. The secondary lever N is located adjacent the actuator G and is mounted on a pivot stud n projecting laterally from the actuator G through a clearance aperture 9 formed in the body portion of the actuator G being forked at its upper extremity to engage a pin g projecting from the contiguous side face of the actuator G According to this arrangement, when the lower end of the primary lever N is pulled forwardly from the position shown in Fig. 8 to that shown in Fig. 12, said lever will at first have an idle swinging movement in a counter-clockwise direction about the cross pin N as an axis until the weight N passes dead center and the roller n on the shaft N engages the front end wall of the slot 21 (see dotted lines Fig. 8). Thereafter, the weight N by force of gravity, is adapted to swing the lever N further in the same direction but this time about the shaft N as an axis. This further and active swinging movement of the lever N is imparted to the secondary lever N through the link N and eifects a reversal of the actuators to their position shown in Fig. 12. As a result, the front end of the rocking lever H will be swung downwardly, either by the engagement of the projecting ear g of the actuator G with the stud h of the lever H, or by the engagement of the projecting ear g of the actuator G with the stud h of said lever, depending of course upon the vertical position of the reciprocating slide G and the direction in which it happens to be moving at the time. If now the lower end of the primary lever N is pushed rearwardly until the roller 12 engages the rear end of the slot v the weight N in passing dead center will swing the lever N in the opposite direction and restore the actuators to their original position. In such instance, the front end of the rocking lever H will be swung upwardly from the position shown in Fig. 12 to that shown in Fig. 8, either by the engagement of the projecting ear g of the actuator G with the stud 71?, or by the engagement of the projecting ear 9 of the actuator G with the stud h In both instances, the stop pin G on the slide G, by its engagement with a side wall of the aperture G of the actuator G or by its engagement with one of the end walls of the open slot G of the actuator G determines not only the reversed angular positions of the actuators but also, though indirectly, the angular positions of the primary lever N. In this connection, it may be stated by way of explanation that the arrest of one of the actuators at the time of the reversing operation would not interfere with the full movement of the other, so that it may function without delay in bringing about the adjustments of the throat section C and the lever support F Such a condition is illustrated in Fig. 10 which shows the parts in the position they assume whenever the primary lever N is swung toward the left while the reciprocating slide G is in its lowermost position, the actuator G being arrested in its swinging movement by the stud h of the lever H, and the actuator G having completed its swinging movement and thus occupying a position beneath the stud h 50 as to actuate said lever as the slide begins to rise. A similar condition would result if the primary lever were swung in the opposite direction while the slide G was in its uppermost position, except at this time the actuator G would be momentarily arrested in its swinging movement by the stud h' of the lever H while the actuator G would be allowed to complete its swinging movement and function as the slide started its descent.

It will now be clear that, as soon as the primary lever N is actuated and irrespective of the vertical position of the slide G or the direction in which it is moving, the operation of the rocking lever H and the adjustment of the throat section C as well as the support F will be instantly efiected in the manner stated. Moreover, the use of an eccentric for operating the slide, in conjunction with a friction clutch for driving the eccentric, insures smoothness in the operation of the parts and avoids unnecessary noise or pounding that might otherwise result as the throat section is swung to and from its adjusted positions against the banking screw u and the stop shoulder t.

Operation of the primary or weighted lever N (see Figs. 1-6 and 10) is controlled from a finger piece or key P fastened to one end of a horizontally disposed rod P and arranged conveniently adjacent the keyboard E. At its opposite end, the rod P is rigidly secured to and supported by an arm P extending forwardly from the hub portion of a T-shaped lever P which is pivotally mounted on a cross pin 71 between upstanding members H of the fixed bearing bracket H before referred to. The vertical or depending arm P of the lever P is operatively connected with the primary lever N through the medium of a vertically disposed lever P pivoted to the fixed housing bracket V and attached by means of a fore-and-aft link P with the small shaft N at the lower end of the lever N. By depressing the finger key P, the primary lever N (see Fig. 10) will be swung rearwardly and condition the parts in the manner already described to effect the rearward adjustment of the throat section C and the lever support F and, conversely, when the finger key is raised, the lever N will be swung forwardly (see Fig. 8) and condition the parts to reverse the adjustment of the said throat section and support. To facilitate the operation of the finger key P, the lever P is provided with a coun'terbalancing weight P carried by a rearward extension of the arm P and adapted to neutralize the weight of the relatively long key rod P Reference is now directed to Figs. 1, 4, 5, '7 and 14, which illustrate the automatic means for locking the throat section C in its difierent adjusted positions and for releasing it preparatory to its adjustments. Such means (best shown in Figs. 4 and 5) includes a vertically disposed latch element R centrally pivoted to a small bracket R and controlled by the operation of the lever J which, for this purpose, is equipped with an antifriction roller J arranged to engage upper and lower beveled or cam surfaces R R and R R formed on the front edge of the latch element. The bracket R is secured to the rear side of the upright bracket U near the top and is designed to house a pair of spring plungers R R whose stem portions project a limited distance through the front wall of the bracket and engage the rear edge of the latch element R at points above and below its pivotal axis, The plungers R, will thus sustain the latch element in its vertical position (Fig. 4) but will permit the upper and lower portions thereof to yield rearwardly in opposition to the plungers when the lever J is operated in order to carry a pair of spaced apart banking studs R R out of the path of a hardened block C protruding from the free end of the crank arm C The studs R. and R are mounted transversely in lateral projecting ears R of the latch element and are adapted to engage the block 0 and lock the crank arm against operation in the different adjusted positions of the throat section C The relation of the parts is such that, as the lever J is swung downwardly by the vertical rod J to effect a rearward adjustment of the throat section C the roller J (as permitted by the angular slot C in the crank arm C will first cam the upper portion of the latch element R rearwardly in opposition to the plunger R (from the position shown in Fig. 4 to that shown in Fig. 5), and thus release the crank arm by removing the upper stud R from its locking position beneath the block As the lever J continues its downward movement, the roller J will next cam the lower portion of the latch element rearwardly to carry the lower stud R out of the path of the block C but finally, as the set screw 0 of the throat section banks against the stop shoulder 25, allow the latch element to resume its vertical position under the influence of the plunger RF and carry the stud R to its locking position above the block C When the lever J is swung upwardly in effecting a forward adjustment of the throat section C the lower portion of the latch element R, preparatory to the operation of the crank arm C will be cammed rearwardly to release the crank arm and then, as the latter engages the banking screw u, the latch element will be allowed again to resume its vertical position (Fig. 4) under the influence of the plunger B. so as to locate the stud R once more in its original locking position beneath the block C At such times, the weight 71. at the rear end of the rocking lever H is adapted to counterbalance the weight of the vertical rod J and thus overcome its tendency to actuate the latch element R and inadvertently release the crank arm D The turn buckle J near the upper end of the rod J, permits the latter at the time of assemblage to be adjusted longitudinally to the exact length required.

While the improved power mechanism has been herein shown and described as employed for the adjustment of the throat section C and the lever support F it will be understood that it could be employed equally as well for the adjustment of some other operative organ of the machine, and particularly if such organ (like the throat section C and the lever support F is required to be adjusted back and forth between different set positions.

In or for a typographical composing machine equipped with an operative organ adjustable back and forth between two diiferent positions of rest, power mechanism including, in combination, a constantly reciprocating member normall free to reciprocate without efifect upon the o erative organ in either of its two different positions of rest, and selectively controlled means acting, upon successive actuations only, to cause said constantly reciprocating member to eifect the reverse adjustments of the operative organ during either stroke of said member.

24. In or for a typographical composing machine equipped with an operative organ adjust-- able back and forth between two different positions of rest, power mechanism including, in combination, a constantly reciprocating member, a pair of actuating elements carried thereby and reversible in operative position with each other in effecting the reverse adjustments of the operative organ, and selectively controlled means acting, at each actuation, to eiiect a reversal in operative position of the actuating elements.

25. In or for a typographical composing machine equipped With an operative organ adjustable in one direction or the other to different set positions, power mechanism including, in combination, a single constantly reciprocating device adapted b its two-way movement to adjust the operative organ in either direction, and means actuatable selectively for conditioning said device t effect the individual adjustments of the operative organ and allow said organ to remain in any set position until again conditioned by a subsequent selective actuation of said conditioning means.

26. In or for a typographical composing machine equipped with an operative organ adjustable to one or the other of two different positions. power mechanism including, in combination, a pair of actuating elements mounted to reciprocate constantly as a unit while occupying a fixed predetermined relationship to each other to efiect the adjustment of the operative organ to one of its two difierent positions, and means actuatable sepredetermined relationship to each other to effect the adjustment of the operative organ to one of its two different positions, and means actuatable selectively for reversing the operative position of the two reciprocating actuating elements with respect to each other in creating a different fixed predetermined relationship between them to cause them to efiect the adjustment of the operative organ to the other of its two different 10 positions.
